Unlocking the Remaining Potential of the UKCS

The oil and gas services industry has seen the recent arrival of broadband seismic technologies. Broadband data contain a wider range of frequencies, from 2.5-200 Hz and above, while conventional seismic data typically lacks frequencies between 2-7 Hz and above 80 Hz. In the search for ever more geological resolution broadband seismic now gives the interpreter additional information in the form of stunning, high resolution images of the subsurface. Details are enhanced thanks to the high frequency content of the signal and depth of penetration is increased thanks to the low frequencies. In a mature basin such as the North Sea broadband seismic provides significant enhancements in a range of environments: exploring for new stratigraphic plays and subtle structural closures and enhancing further hydrocarbon recovery by giving more detailed information about local facies variations and reservoir compartmentalization. After introducing the broadband solution developed by CGGVeritas, we expose here, with concrete examples, some of the many benefits that broadband data brings to seismic interpreters.
